The bluets (Genera Coenagrion and Enallagma) are the small black-and-blue damselflies seen in the vegetation along lakes, ponds, marshes and streams throughout the summer. Females may be green, blue or tan marked heavily with black. Most species require close examination of the claspers to identify them. A few, such as Stream Bluet, Skimming Bluet, and Taiga Bluet have a distinctive enough abdominal pattern to be identified without a magnifying lens. Others, such as the Rainbow Bluet, have additional colours on the body which makes them the easiest to identify.
